A study of the interaction between alfalfa (Medicago sativa) and one of its fungal pathogens, Colletotrichum trifolii.
(2001)
The alfalfa/C. trifolii interaction follows a gene-for-gene interaction for race-cultivar specificity where in general, products of host resistance genes providing resistance to the fungus are interacting with direct or ...
Cloning, characterization, expression and localization of inosine-5'-monophosphate dehydrogenase (IMPDH) cDNA/mRNA in soybean (Glycine max) nodules.
(2000)
The technique of in situ hybridization was used to localize the IMPDH mRNA in soybean nodules. Mature nodules were fixed in 4% paraformaldehyde and 0.25% glutaraldehyde, dehydrated and embedded in Paraplast. Sections of ...
The reduction of uranium by sulfate-reducing bacteria in the terrestrial subsurface and a pure culture bacterium.
(2002)
The microbial reduction of uranium was investigated in a contaminated aquifer and with a pure culture model organism, Desulfovibrio vulgaris Hildenborough. The concentrations of Fe(III), U(VI), nitrate and sulfate were ...
Cell-cell interactions in Myxococcus xanthus.
(2004)
Myxococcus xanthus, a Gram-negative, rod-shaped, nonpathogenic soil bacterium has been used as a model organism for many years for research on developmental behavior such as multicellular morphogenesis, signal transduction. ...
Bacillus mojavensis and Bacillus subtilis require DNA or deoxyribonucleosides for anaerobic growth.
(2004)
Bacillus mojavensis strain JF-2 grows to an A600 of 0.8 to 1.0 in aerobic medium E but growth in this medium under strict anaerobic conditions is difficult to establish and replicate. Anaerobic growth of JF-2 was not ...
Cytosolic delivery of mutant forms of toxin B from Clostridium difficile facilitates characterization of the intracellular activities of large clostridal toxins.
(2002)
Clostridia are gram-positive spore-forming organisms responsible for a variety of diseases in both humans and animals Three species of Clostridia- Clostridium difficile, Clostridium sordellii and Clostridium novyi- produce ...
Peripheral and central pathways involved in the biodegradation of monoaromatic compounds under anaerobic conditions.
(2001)
Overall, the work in this dissertation contributes to our understanding of anaerobic biodegradation pathways, the role of syntrophic interactions in substrates degradation, and demonstrates a novel benzoate fermentation ...
The microbial metabolism of benzene and crude oil under diverse anaerobic conditions.
(2000)
The research reported here expands the range of knowledge for anaerobic hydrocarbon metabolism, as well as provides a sound foundation for the microbial destruction of compounds once thought to be completely recalcitrant ...
Genes required for sediment fitness in Desulfovibrio desulfuricans G20.
(2007)
97 genes required for sediment fitness of G20 were identified and the identification of chemotaxis genes validated our STM screening method since it would be expected to enhance sediment fitness. The growth of these sediment ...
Iron uptake in Gram-negative and Gram-positive bacteria.
(2006)
Bacteria, including both Gram-positive and Gram-negative bacteria, utilize iron sources from the environment. Iron uptake systems in Gram-negative bacteria are well studied. Escherichia coli FepA transports certain catecholate ...
